Job Description Summary
Performs complex (journey-level) to advanced (senior-level), geosciences or hydrological work. Work involves the compilation and documentation of source information; adherence to set processes and standards; the use and manipulation of various programming scripts; development and calibration of numerical groundwater flow models; analysis and interpretation of groundwater modeling results and water budgets; the use of GIS software to prepare maps, geodatabases, process data, and/or review input/output from models; writing reports; providing presentations; reviewing, analyzing, coordinating, or overseeing the collection and analysis of data and samples for technical reports and projects; preparing, reviewing, or evaluating model designs, results, and analysis and reports; and ensuring compliance with applicable statutes and regulations. May train or supervise others. Works under general to minimal supervision, with limited to considerable latitude for the use of initiative and independent judgment. Reports to the Manager of the Groundwater Availability Modeling Department.
